Chapter 444: Chapter 264: Good News: Selected for the Finals of the National Cardiac Surgery Skills Competition
"22F long guiding sheath... 5,000 units of heparin..."
Huang Dian swiftly assisted, his excitement palpable as he participated in the surgery. This was another brand-new, domestically produced aortic valve replacement technology.
After injecting the arterial heparin, Wu Ting created an auxiliary access point in Lou Musaang’s left femoral artery.
Then, Wu Ting employed a highly complex technique for the aortic root angiography.
Shen Siyuan watched his student with a look of amazed admiration.
’This kid... How long has he been at this? To have already mastered the short-axis projection for a type 0 bicuspid aortic valve so skillfully...’
Shao Yuqiao was equally astounded by Wu Ting’s clinical genius.
Only by being here for this second-stage surgery could one truly understand that, beyond his paradigm-shifting new and improved Surgical Technique, Wu Ting’s fundamental clinical skills were on par with any director-level physician.
"AL2 catheter... Straight-tip ultra-smooth guidewire..."
Watching Wu Ting perform another highly complex maneuver, the others couldn’t help but marvel.
Wu Ting used an ultra-smooth guidewire to cross the valve. Once across, he exchanged it for an S-shaped, pre-formed Angelguide working guidewire—a difficult, atraumatic technique.
"The proprietary 20-millimeter balloon..."
And now, it was time to showcase the R&D and innovative capabilities of Wu Ting’s team!
Its brilliant debut!
This was a new-material balloon, independently developed and produced by leveraging the deep material science expertise of Weixing Petrochemical. It was capable of performing an atraumatic pre-dilation of the narrow, calcified aorta!
Then came the most thrilling part.
The controllable, adjustable, self-expanding valve delivery system that Wu Ting had spearheaded made its debut!
Wu Ting guided the delivery system into the thoracic aorta. Faced with the complex, deformed vessel, he activated the intelligent, adjustable control system.
Unlike a conventional tip, the one Wu Ting had designed was like a flexible snake’s head. With its angle under precise control, it navigated through the aortic arch and aortic valve.
A conventional tip relies entirely on the operator’s manipulation and force to be advanced, whereas this automated tip simply "burrowed" its way through.
This design eliminated the difficulty of passing the valve delivery system through the aortic arch and across the aortic valve, and it also prevented damage to the aortic wall from the application of excessive force.
Of course, once it reached the correct position, the most difficult challenge was achieving coaxial alignment between the valve and the annulus!
The brand-new, controllable, adjustable, self-expanding valve delivery system once again demonstrated its superiority—an intelligence and precision a generation ahead of traditional systems!
Director Shao and Shen Siyuan kept their eyes glued to the aortic root angiogram.
"Incredible, Wu Ting. This system of yours is absolutely perfect."
"It ensures perfect valve positioning, and there’s not a trace of paravalvular leakage."
After achieving precise positioning, Wu Ting unlocked the retrieval-limiting slider and fully deployed the valve.
This was another new design by Wu Ting and President Liang, for which a patent application had already been filed.
This design allowed the valve to remain coaxial throughout deployment, eliminating the need for dynamic adjustments to the delivery system’s tip. When it was time to remove the device from the aorta and aortic arch, the system could be smoothly retracted and withdrawn from the body.
An excited Director Shao instructed Huang Dian to begin a simultaneous check.
Huang Dian quickly called out the results:
"Despite severe aortic calcification, the prosthetic valve’s placement and morphology are perfect..."
"Final aortic root angiography shows the newly implanted valve is in an ideal position with no paravalvular leak..."
"Transesophageal echocardiogram shows good bioprosthetic valve motion, an orifice area of approximately 1.5 cm2, a peak velocity of 203 cm/s, a mean transvalvular pressure gradient of 9.5 mmHg, and no paravalvular leak..."
"Director Wu, Director Shao, Director Shen, the surgery was a success!"
"The controllable, adjustable, self-expanding valve delivery system had a flawless debut!"
Amid Huang Dian’s cheers, the two directors were also overcome with excitement.
"This is an extraordinary achievement!"
Shao Yuqiao knew exactly how significant this research was. It looked like Wu Ting was going to cause another major sensation at the upcoming National Cardiothoracic Surgery Skills Competition!
And this was in combination with the fourth-generation bioresorbable polymer vascular stent from the first stage. In other words, Wu Ting had single-handedly advanced and perfected the precision of aortic valve replacement surgery!
Aortic valve replacement had long been a mainstream, flourishing technology, both in China and internationally. For years, achieving high-precision valve replacement and a perfect surgical outcome has been the shared goal of doctors and patients alike.
Coaxial misalignment during the Surgical Technique and trauma to the aortic wall from tip delivery had long been persistent clinical challenges, plaguing countless doctors both at home and abroad.
Who would have thought that Wu Ting, through multidisciplinary research, collaboration on special material processes with Weixing Petrochemical, and support from top-tier algorithms, would successfully create the controllable, adjustable, self-expanding valve delivery system.
"Wu Ting, this is the world’s first controllable, adjustable, self-expanding valve delivery system. I’ve never seen a device that can so easily traverse the aortic arch and a stenotic, calcified aortic valve. To then be able to adjust the delivery tip and achieve precise, coaxial positioning of a VitaFlow III valve at the annular level to successfully complete the surgery... It’s just extraordinary."
Shen Siyuan was equally lavish with his praise and admiration.
"Wu Ting, I’m truly looking forward to this National Cardiothoracic Surgery Competition!"
"It is truly my honor to be your teacher."
The surgery was a complete success.
Lou Musaang could finally return to a normal life and his work.
After the surgery, Wu Ting began preparing the surgical video for the competition and compiling the necessary documentation.
Huang Dian was also tasked with organizing and compiling the data from every stage of Lou Musaang’s two-part treatment process.
...
...
While Wu Ting’s team was making their final preparations and consolidating their work.
Wu Ting received a congratulatory phone call from Director Li Qing of the province.
The very next morning, Jin Province issued a "Decision on Commending Young and Middle-Aged Experts with Outstanding Contributions," conferring upon Wu Ting and 49 others the title of "2024 Jin Province Young and Middle-Aged Expert with Outstanding Contributions."
